When you're talking to a girl, tell her about your vacation, or dog, or that time you met Mark Hamil, and take out your phone to show her the picture. As you're showing her some pictures, say, "do you have intsagram." If they do, open the IG search and hand them your phone. Tell them to find themselves.

Important : don't just grab their contact and bounce. Hang out and continue talking.

BTW : I'm not saying this is great way to run game or will have a high conversion. But, if you are new to this, you gotta start somewhere.

AND : If you are new to this, I just wrote about 4 mindhacks to make approaching way less scary.

Very Important : If you follow her IG and she doesn't follow you back within a day or two, unfollow her. Don't like or comment on her selfies or thirst trap pictures. Occasionally ping with a like to see if she'll reciprocate, and just be normal and chill in DMs.
